ATTIC STEP
A step for installation into an attic that is easily installed on the existing beams within a typical attic to provide a safer and easier means to maneuver within a home's attic space. The step is produced using a single piece of sheet metal. In addition, the step is installed into the attic by securing teeth on the bendable tabs of the step to the existing beams using a hammer with the optional use of additional fasteners.
The present application is related to co-pending U.S. Provisional Application No. 61/895,637, filed Oct. 25, 2013, entitled ATTIC STEP, which is incorporated herein by reference, and claims priority thereto under 35 U.S.C. §119.
BACKGROUND OF THE INVENTIONThe present invention relates to an attic step, and in particular to an attic step that can be fastened to the existing truss beams typically found in attics.
People need to maneuver around within a home's attic space during home construction and for maintenance and inspection requirements in existing homes. Because ceilings are attached to the underside of trusses, people have to be careful where they step in attics so as to avoid falling through or damaging the ceiling. This task can be particularly difficult when insulation covers part of or all of the ceiling, thereby making it more difficult for the person to determine where to step while moving around in the attic. The difficulty with this task can be enhanced when a portion of the trusses are also covered by insulation thereby making it unclear whether there is a board to step onto while moving around within the attic.
Some people step into the V-shape where beams of the trusses meet, as a means for maneuvering in the attic. However, this approach is both inconvenient and dangerous as the person's foot is wedged at an angle and into a potential pinch point between the wooden beams of the trusses. Alternatively, permanent lumber can be installed on the horizontal portion of the trusses. However, installation of permanent lumber is time-consuming and expensive and also compresses the limits to the amount of insulation that can be used in the attic. The installation of permanent lumber can also add weight above the ceiling, thereby increasing the chances of the plaster or drywall cracking. It can also potentially restrict the expansion and contraction of the truss structure which can cause cracks in the plaster or drywall of the ceiling. Yet another way has been to use loose boards in the attic space and move them across the attic while a person attempts to traverse across the space. This too can be cumbersome and time-consuming and also compresses the insulation.
While there are known ways for people to traverse around within an attic, improvements to products and methods for moving around the attic would be clearly advantageous, and are disclosed herein.
SUMMARY OF THE INVENTIONAccording to one aspect of the present invention, an attic step includes a base with a plurality of flanges extending from at least one side of the base. The flanges are spaced apart to closely receive a truss beam. The attic step also includes a plurality of tabs extending from the base, with a plurality of teeth extending from the tabs.
According to another aspect of the present invention, a method for installing attic steps in an attic includes forming an attic step from a single piece of metal. The step includes a base with two flanges extending from the left and right sides of the base. The flanges on each side are spaced apart to create a gap between the flanges. The step also has a tab extending from the left and right sides of the base. The step is placed over a truss such that at least one beam of the truss is closely received in the gap between the flanges on the left and/or right sides of the base. One or both tabs are bent to closely engage the truss beam(s).
According to yet another aspect of the invention, a method of manufacturing an attic step includes selecting a piece of metal stock and stamping the piece to form a one-piece attic step. The attic step has a base, two flanges extending from the left and right sides of the base, a tab extending from the left and right sides of the base, and a plurality of teeth extend from each tab.
The attic step can include any combination of one or more of the following features:
-
- Stamped sheet metal
- An embossed surface that provides strength to the sheet metal while also providing an anti-slip surface
- Flanges to provide rotational support of the step
- Bendable tabs with built-in teeth for securing the step to wood trusses
- Fastener holes through which fasteners can be inserted into the attic step to secure it to truss beam(s)
- Alternative mounting configurations
- Installation accomplished by using a hammer
- A design that allows the attic steps to be stackable for ease of storage, transportation, or display of multiple attic steps.
- A rubberized surface added to all of or a portion of the attic step to enhance the traction and/or durability of the attic step.
These and other advantages of the invention will be further understood and appreciated by those skilled in the art by referencing the following written specification, claims, and appended drawings.
